STEPHEN B. MOB/SS, OF RAHWAY, NEW JERSEY.

LAMP-BURNER.

To all whom it may concern;

Be it known that I, STEPHEN B. Morass, a citizen of the United States, and resident of Rahway, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a specification.

My invention relates to improvements in burners for lamps or stoves, and has for its object to provide improved means for causing generation of gas from oil drawn up by or through the wick to increase the brilliancy of the light, improve combustion of the flame, and serve to reduce relative consumption of oil.

In carrying out my invention I provide wick casing tubes with a wick therebetween, and an air passage within the inner wick tube and exterior to the usual central draft for air supply to the perforated distributer or thimble, and over or upon the wick 1 provide a flange adapted to be raised and lowcred by the wick, which flange extends across said air passage and is provided with one or more openings to permit the escape of air from such passages to the flame at the top of the wick, and that is generated at the inner surface of the wick at its top below the flange flows out through such openings with the air from said passage and commingles with the flame from the Wick, the arrangement being such that said gas passes from the wick in the space between the latter and the perforated air distributer. Said flange has an inwardly extending portion provided with said openings and guided by the central draft tube to rise and fall with the wick, said tube serving as a guide for the flange. The passage above named receives air from below in manner similar to the air received by the central draft tube, and the air from said tube passing through the perforated distributer passes to the flame in usual manner. Said flange also serves as an extinguisher when the wick is lowered as well as a gas generator.

My invention also comprises the novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure l is a vertical section of a burner embodying my invention; Fig. 2 is a detail perspective view ofthe gas generator and extinguisher; Fig. 3 is a central section of a Specification of Letters Patent.

modified form of the burner; Fig. l is a cross section on the line i, a, in Fig. 3, and Fig. 5 is a perspective of the gas generator or burner showing elongated openings for the escape of gas.

Similar ntunerals of reference indicate corresponding parts in the several views.

The numerals, 1, 2 indicate concentric tubes between which the wick 3 is located, and at 4: is a central draft tube arranged at a suitable distance from and within the in ner wick tube 2 providing a passage 5 between the tubes 2 and l. The passage 5 and the bore of tube 4 receive air from below, as through the oil font, in any well known manner.

At 6 is a flange or ring, preferably of metal, adapted to rest over and upon wick 3 and the inner tube 2, which flange or ring has an inwardly extending portion 6 shown guided upon tube 4: and fitted freely so as to rise and descend and to be guided by said tube. The intermediate or inwardly extending portion 6 of flange 6, to which the guiding portion 6 is connected, is provided with one or more openings 6 which are in line with passage 5 to permit the flow of air and gases through said passage to commingle with the flame from the wick. The openings 6 may be circular, or may be elongated as in Fig. 5, or otherwise suitably ar ranged, and any desired number of such openings may be provided. The parts 6, 6 and 6 constitute what I term a gas generator and extinguisher, as when said parts are heated by the flame they serve to aid in generating gases at the inner portion of the wick that extends above inner tube 2 when the wick is raised, which gas flows out through the openings 6 and aids in causing a draft upwardly through passage 5.

At 7 is a suitable perforated air distributer or thimble receiving air from the central draft tube 4. The portion 6 of the generator and extinguisher is shown inwardly beveled or inclined so as to rise a suitable distance before engagement with distributer 7 whereby the wick may be raised a suitable distance, and the part 6, as shown, is adapted to engage distributer 7 to thereby limit the raising of the wick. Distributer 7 as shown in Fig. 1 is provided with extension 7 fitting tube t, and at 8 is a rod connected with tube 4, as by arms or a spider 9, which rod extends upwardly through distributer 7 the latter being secured to said rod, whereby the upward movement of the distributer by the gas generator and extinguisher is prevented. Distributer 7 may be secured to rod 8 by having a threaded opening secured upon the threaded end f5 of such rod or by a nut on said threaded end.

Instead of tube t extending completely through the inner tube 2 at the bottom, said tube t may extend partly through the tube 2. In Fig. 8 1 have shown tube at as secured to rod 8 and provided with lower openings i to receive air from below or from tube 2, to which tube arms 9 are secured, and in the construction of Fig. 3 the tube t and the distributer 7 are shown as united or made in a single piece. The lower part of tube l is shown resting upon a collar or shoulder 10 on rod 8, whereby tube e and the distributor are sustained.

Then the wick is raised and lighted the flame burns upon the outer upper exposed portion of the same in usual manner, the air passing up within central draft tube a and through the perforations of the distributer 7 supplies air to the flame as usual, and the heated gas-generator and other parts cause gas to be formed at the upper inner portion of the wick above tube 2, which gas mingles with air flowing up passages 5, and such gas and air mixture burns as a flame above the openings 6 and passes over the flange of the generator to and mingles with the flame from the oil at the wick, resulting in increasing the brilliancy of the light and aiding combustion of the flame from the oil.

The air flowing up through passage 5 will be more or less heated, and as such air mingles with the gas generated above tube 2 at the upper inner portion of the wick and flowing through openings 6 such mingled air and gas will burn in the nature of a blue flame. Furthermore, the heated air flowing from the air distributer ano particularly from the lower openings thereof, in passing over the space above the perforations 6 in the gas generator, helps to create a current to aid in drawing the gas and air out of the upper part of passage 5, thereby accelerating their upward movement and aiding to increase the generation of gas at the inner upper surface of the wick with corresponding increase in volume of the flame. Owing to the heated state of the generator and the space within the wick at the upper portion of passage 5 the generation into gas of oil brought by the capillary action of the wick to the upper inner surface of the wick is sustained. The openings 6 are to be of suflicient size or area to permit the gas and air mingling below such perforations to pass through the same freely. Owing to the heat of the flame and the combined action of the two currents of heated air, (the one passing up through wick tube 4 and out of the distributer and the other passing up air supply passage 5) meeting above the perforations 6 of the generator, the proper delivery of the air and gas mixture to the oil flame is effected, and the distributer above passage 5 causes such gas and air mixture to be deflected outwardly toward the flame. hen the wick is turned down or lowered the flange 6 will serve as an extinguisher for the flame, and when flange G rests upon tube 2 it will cut off the production of gas at the upper portion of the wick.

Changes may be made in the details of construction and arrangements set forth within the scope of the appended claims without departing from the spirit of my invention.

Having now described my invention what 1 claim is l. A central draft burner provided with an air passage between the central air tube and the inner wick tube, and a gas generator located at the upper part of said passage and having a flange extending from the central air tube over to and upon the wick completely covering saidpassage, said flange having one or more openings to permit the flow of air from said passage and also the gas generated at the upper inner portion of the wick.
